IMPROVEMENT IN APPARATUS FOR EXTRAGTING WOOL FROM MIXED ARTICLES ANDFABRIGS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, ARTHUR Knownns, Janus KNOWLES, and JosnnaBnnnncnouen, all of Bristal, near Leeds, in the county of York, subjectsof Great Britain, have invented or discovered new and usefulImprovements in Means or Apparatus for Extracting Wool from Cotton andother Vegetable Substances contained in Mixed Fabrics, and we, the saidAnrrzun KNOWLES, JAMES Kxownns, and JOSHUA BA'nnAeLouc-u, doherebydeclare the nature of the said invention and in what mannerthe'same is to be performed to be particularly described and ascertainedin and by the following statement thereof; that is to say- The object ofour invention is to destroy the cotton containedin mixed fabrics moreexpeditiously than is now done, and "for this purpose, afterthe usualprocess of steepingathe material in acid, we place the same within acylinder made either ofiron or copper wire and placed over a fire. Thiscylinder slowly revolves on its axis (being actuated by suitablegearing) and is fitted, upon the inner circumference, with eight rows,more or" less, of iron spikes to prevent the material or rags fromrolling and gettingentahgled together. The ends of the, cylinder aremade either of wood or of iron plates, and to each end a, shaft isattached, on which the-cylinder revolves. During its revolutions thecotton is quickly destroyed by the action of the heat. In order,however, to prevent the wool from injury, water, or steam, if preferred,is injected by meansof a perforated pipe or p'ipes into the cylinder insuch quantities as may be desired. When the cotton is suflicientlydestroyed the wool resulting from the operation is cleansed from therefuse cotton and acid. By thismethod the cotton is both more quicklyand thoroughly destroyedthari hitherto, and thelstrength of the wool notimpaired.

In order, however, that our invention may he more thoroughly-understood,reference is made to the accompanying sheet of drawings, and letters andfigures marked thereon, similar letters representing similar parts; thatis to sey i I Description of the Drawings.

Figure 1 is a side elevation of our apparatus.

Figure 2, a vertical section.

Figure 3, a plan; and

Figures; and 5, enlarged transverse section and plan of the heatingtrough.

Letters A represent the standards used for supportiag the cylinder, suchstandards being a part of or bolted to the foundation plate A. Letters13 represent the rotating cylinder-{having ends made of wood or iron(into which the wire covering 0 issecur'ed) and resting upon axes, b, instandards A, one of the axes having a. pulley, B, for the purpose ofdriving, (wherebelting is used.) On reference to fig. 1 it will be seenthat a portion of the wire covering (sny'one-eighth part) extending fromc to e is made to open on hinges for the purpose of charging anddischarging the cylinder with the material ,to be operated upon.Referring to fig. 2, the iron spikes d (omitted in-figs. 1 and 3 toprevent confusion) are shown. These prevent the entangling of thematerials. Letters D represent the heating trough, in which the firerests on bars (1. This trough is furnished with a movable flnp,.d which,when in position as shown in fig. 2, partially prevents the escape ofheat. The axles e, having wheels e, support the trough, and by means ofthe handlesf the same is placed in position or withdrawn from under thecylinder, when the same is not in motion, the projections 02 on thefoundation plate guiding the wheels; Letters 9 show the perforated piperesting on supports g, secured totho standards A, and furnished withwater or steam, as desired, by communicating pipe g". I

The materials to be operated upon (saturated as before explained) beingsupplied to the cylinder, the latter is caused to rotate, and the fire(the draught of which may beurged by a blast pipe from an ordinary fan)placed underneath, steam or water being simultaneously admitted to thecylinder, if desired, by means of the perforated pipe before named. Bythe action of the heat the cotton is destroyed and the wool remains. Thewool is then removed, washed, and dried by the customary methods, and isagain fit for manufacturing purposes.

Having now fully disclosed thenature of'our invention, and in whatmanner the same may be performed, we would have it understood that whatwe claim as of our invention, is p The means or apparatus shown anddescribed for the purpose of extracting wool from cotton and othervegetable substances contained in mixed fabrics.
